Sounds like you have range problem, more likely than not based on your comments the TX maybe the problem. Why not return it to Hitec Service for evaluation. Be sure and include the TX modules in use, I would also send in the RX's if possible. Better safe than sorry.
You mention "almost unflyable with a 100' range". Antenna down range check or?
It is going back again this week. I already sent it away once with 2 of the rxs.
the antenna is fully extended, still only 100ft range.
Im thinking of swapping to 72mhz anyhow so that may help.
I have tryed futuba rxs in place of the rx and things improved a little but still glitchy with limited range.
For some reason the gws rx seem to have the least glitches and the greatest range. I dont know why. They still arent perfect, but without doubt the best so far.
